MafB is a conserved transcriptional regulator of macrophage development and functional identity across tissues and speciesImmunity · 2026
Summary (written by the submitters)
Resident tissue macrophages (RTM) are characterized by a remarkable diversity but also share common features that are thought to be driven by conserved transcriptional programs. While the transcription factor MafB is highly expressed in the macrophage lineage, little is known about its role in establishing RTM identities. Here, we show that the absence of MafB results in a profound imbalance across many RTM populations and in a disruption of global and tissue-specific RTM signatures in mice.

Furthermore, we found that MafB was required for the differentiation of bone-marrow-derived macrophages (BMDMs) ex vivo and of RTM populations from monocytes in vivo. Mechanistically, epigenetic profiling of MafB binding sites in BMDMs revealed that MafB directly regulated expression of key RTM differentiation and identity genes, including Csf1r and Fcgr1. Finally, in silico analyses showed that MafB binding sites were highly conserved across vertebrates. Our findings demonstrate the crucial and evolutionarily conserved role of MafB as regulator of RTM development and identity, connecting MafB-dependent transcriptional programs with unique defining features of RTM.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE287346_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1212172 and SRA study SRP558116. Searching any of these in the dataset finder brings you back here.
